I am talking on this topic courtesy of the 21st Century Network on Thursday, 24 February at 7.30pm GMT (that's London time, use a TimeZone Converter to see when this is for you).
A shared base income is something I've written on in The Common Purpose Manifesto. It arose out of trying to create a system in which everyone can live fulfilling lives without harm.
The shared base income fits into the broader scheme of the unconditional basic income, known variably as the guaranteed income, universal income, and so on. I'll be broadly introducing the concept and talking a little about this and the shared base income.
Anyone is welcome, but you'll need to RSVP on the 21st Century Network's Meetup site. Follow the link here to do this: http://www.meetup.com/21stCenturyNetwork/events/16103771/
